Long WPC cladding boards should be stored horizontally on flat, properly supported surfaces, away from direct sunlight and excessive heat. Cartons must follow the manufacturer's stacking limits, and individual boards should be lifted rather than dragged to protect their surfaces and edges.
For WPC importers, wholesalers, and distributors, proper warehouse storage helps maintain product condition throughout receiving, inventory management, and dispatch. The following guidance follows MATECO's storage requirements.
Key Takeaways
• Store long boards flat on level supports; avoid unsupported spans.
• Avoid direct sunlight and storage temperatures above 60°C .
• For long-term storage, stack no more than 12 cartons under the specified conditions.
• The 16-carton limit applies only to specified short-term site storage of up to 10 days.
• Lift boards rather than dragging them; cover and label opened stock, without using transparent repackaging materials.
1. Inspect Cladding Packs Before Storage
Check incoming shipments before placing them in warehouse inventory.
• Verify the profile, color, length, quantity, and batch labels.
• Inspect cartons, pallets, and straps for visible damage or shifting.
• Check exposed board ends for impact damage, unusual bending, or moisture exposure.
• Photograph and separate questionable stock for further assessment.
Early inspection helps prevent damaged or incorrectly identified products from entering normal inventory.
2. Store Long Boards Flat with Proper Support
MATECO recommends storing WPC cladding boards horizontally on flat, level supports.
Long boards should not be supported only at their ends while leaving a large section unsupported in the middle. Uneven pallets or incorrectly positioned support blocks can also create unnecessary stress on boards and packaging.
Before storage, confirm that:
• Pallets and supporting surfaces are level and undamaged.
• Supports are properly arranged along the board length.
• Cartons do not extend beyond their supports without adequate reinforcement.
• Storage racks and pallets can accommodate the pack dimensions and weight.
Important: Installation batten spacing is not the same as warehouse storage support spacing. Confirm product-specific support requirements with MATECO WPC when necessary.
3. Avoid Direct Sunlight and Excessive Heat
Store WPC cladding cartons indoors or under suitable roof coverage whenever possible. Avoid prolonged direct sunlight, especially near warehouse entrances and exposed loading areas.
According to MATECO WPC's storage instructions, storage temperatures should not exceed 60°C.
Keep packaging away from standing water, roof leaks, and unnecessary dirt. Although WPC cladding is intended for outdoor applications, packaged inventory still requires appropriate storage protection.
4. Follow MATECO WPC's Carton Stacking Limits
Stacking limits depend on storage duration and conditions.
| Storage Condition | Maximum Stacking |
|---|---|
| Long-term warehouse storage | 12 cartons |
| Short-term site storage (up to 10 days) | 16 cartons |
| Opened or damaged cartons | Requires separate assessment |
The 16-carton allowance applies to the specified short-term site conditions and should not be treated as a general warehouse stacking limit.
These limits apply only under the relevant MATECO WPC packaging and storage conditions. Pallet, rack, and floor load capacities must also be checked.
5. Handle Full Packs and Individual Boards Carefully
Moving Full Packs
Before moving a complete pack, confirm that its packaging is secure and the handling route is clear. Use equipment suitable for the pack's weight and length. Keep the load adequately supported and prevent cartons from sliding or striking surrounding objects.
Forklift capacity and load-support arrangements should be selected according to the actual packaging specifications.
Handling Individual Boards
When removing individual cladding boards:
• Lift boards instead of dragging them across adjacent surfaces.
• Provide enough support to avoid excessive bending.
• Protect visible surfaces, edges, and connection areas.
• Keep contact surfaces free from sand and debris.
The number of handlers and support points should reflect the board's length, weight, and profile.
6. Protect Opened Cartons and Remaining Stock
Partially picked cartons require additional attention because their original packaging may no longer provide the same protection. Keep remaining boards flat on suitable supports and cover exposed surfaces.
MATECO WPC does not recommend transparent materials for repackaging. Follow the applicable packaging instructions when protecting opened stock.
Retain product information, including profile, color, board length, and batch identification. Clearly label opened cartons and avoid mixing boards of different specifications.
Do not automatically apply full-carton stacking limits to opened or incomplete packaging.
7. Inspect Boards Before Dispatch
Before preparing warehouse stock for shipment:
• Confirm that product labels match the order.
• Check packaging, board ends, edges, and visible surfaces.
• Make sure partially picked stock is properly covered and identified.
• Record any visible damage or unusual bending.
If boards appear bowed or damaged, separate them for assessment and contact MATECO WPC when necessary. Do not attempt to straighten boards using uncontrolled heat or excessive force.

FAQs
Can long WPC cladding boards be stored upright?
MATECO WPC recommends flat, horizontal storage. Upright storage should not be used unless specifically approved for the product.
How closely should long boards be supported?
Support arrangements depend on board length, profile, weight, and packaging. Refer to MATECO WPC's applicable instructions rather than using installation batten spacing.
How many cartons can be stacked in a warehouse?
MATECO WPC specifies a maximum of 12 cartons for long-term storage. The separate 16-carton allowance applies to short-term site storage of up to 10 days under specified conditions.
Should original cartons be removed during storage?
Keep original packaging intact where possible. If cartons are opened, protect the remaining boards and retain their identification labels.
What if stored boards appear bowed?
Document the condition, separate affected stock, and contact MATECO WPC for assessment before dispatch.
Conclusion
Proper storage of long WPC cladding boards requires level support, controlled stacking, suitable environmental protection, and careful handling. These practices help wholesalers, importers, and distributors maintain product condition throughout warehouse operations.
